Should i use teeth whitening strips before or after brushing

Use whitening strips on clean, dry teeth according to their instructions, but avoid brushing immediately before application because it can irritate the gums.

Whitening strips are flexible plastic strips coated with a peroxide gel. They sit against enamel for a timed period, allowing the gel to contact stain molecules on the tooth surface.

Brushing immediately before use may make gum tissue more sensitive, especially with a firm brush or vigorous technique. Cleaning earlier and applying the strips to dry teeth can reduce saliva dilution without scrubbing the gums first.

Brush at another time with a soft brush, floss gently, and follow the strip instructions for wear time. Do not sleep in strips or use them on painful teeth, untreated decay, or irritated gums.

Stop and seek advice for significant burning, gum sloughing, sharp pain, or sensitivity that does not settle. A dentist should assess dark areas, holes, or a single discoloured tooth before whitening.
